Why do you classify it as a "fuel injection noise"? Where is the sound coming from? Front of the engine, rear, left or right? That will help identify the problem.

As for reseting the service intervals, you have a couple options, first and cheapest is going to the Dealership and seeing if they will reset it for free. Second is purchasing the item you see below off ebay for $15. However shipping for mine took 3 weeks.
